Just wondering peoples thoughts. Overpowered. Kites say x wind range per kite size/style per rider weight. I can understand the low end of wind range. I mean if there's no wind the kite just won't fly. But what makes the top end unwieldy?

Is it the fact that the kite won't fly properly, or is it the fact that the kite/lines will break, or is it the fact that the rider will be sent into orbit? I know there is some leeway due to rider experience and board size but at some point there's obviously a breakdown in what is possible. What exactly happens? Why don't riders like to ride seriously overpowered to get their kicks?

Can we use a 12 meter bow kite as the discussion example because that's what I'm familiar with.

yo sweets , ive ridden some big winds with my 9 edge and 11, but have only ever felt overpowered on my catalyst 8 when we copped the backend of cyclone iggy, my meter was reading between 37 to 41 knts gusting to 45,this was when the kite took some seriouse wrestling to crontrol so id say at 45knts it was at its limit , ive witnessed my mate riding in similar winds on a 10mtr vegas and looking in complete control,in the luderitz speed challenge they ride 9mtr and 10mtr kites up to 50knts if you watch the kite on the film it looks a bit twitchy but not uncontrolable,so its hard to say when a kite reaches it limit all i know is i wouldnt wanna be on the end when it does

There's only a certain amount of power you can handle - any more and you lose control by degrees until you're getting tea-bagged (as the term implies, dunked in and out of the water like a tea bag).

To some extent you can reduce the power by reducing the angle of attack (letting the bar out), but it gets very inefficient as the drag remains higher, proportionally to the lift, at sub-optimal angles of attack. So this tends to pull you downwind.

Additionally, as the angle of attack is reduced, an increasing area of the canopy starts to luff (flap) and this greatly reduces its responsiveness to steering input.

In summary, too big a kite is unsafe, unwieldy, unresponsive and no fun. The right sized kite will be faster, jump higher, be safer, more fun, and - when you get to that level - you'll be able to do unhooked stuff on it, whether freestyle, wakestyle or surfing.

Some people think overpowered is when you can no longer control the kite. I say your way past over powered at the point.

My theory for overpowered is this.

You are overpowered when you can no longer flying the kite anywhere in the window without getting hammered. You are getting the hell rib crush.

If you have to adjust the trim strap on your kite to reduce power. Your over powered. At that point if you downsized to the next kite size you will be perfectly powered.

So take my 13m edge. I start to reach for the trim strap around 23 knots. I could still trim away and hold onto the kite until around 30 knots. But at 23 knots i'm in the perfectly powered zone for my 10m C4. So why run rib crushing overpower when i can be perfectly powered and have more fun? The only time i'll do this if the wind builds during the session and i don't have time or can't be arsed changing down.

I certainly will never put up a kite i have to trim and fly unless i missread the wind conditions.

for sure you could use 12M carefully in strong winds , but thats no fun.
more than 1 kite for control at your choosen style .
overpowered is for the very good or the ill equiped .
get a smaller kite there more fun than a 12M IMHO.

I'd tend to disagree with Plummet, there is nothing wrong with trimming your kite, it just allows you to optimise the power available to suit your riding style, skill and stance in any given session. But I would add that if you are getting close to being trimmed all the way in (and leaving yourself little to no safety margin) then you should be putting up a smaller kite or call it quits for the session.

I've got a 12m Convert and a 7 & 9 m Core GT, the GT's have an excellent range on the trim straps compared to the Convert but I don't even consider the 7m until I'm at least halfway trimmed in on the 9m, even then I would be at the absolute bottom end of the wind range in the 7m. I can fly the 9m well into the wind range of the 7m but once I trim in more than half-way it flys like a pig and I don't enjoy it, but that doesn't necessarily make it unsafe or over-powered.

And I know some would argue the GT's fly like pigs regardless of the wind, but I love em, send the 7m and it sure lets you know its there

Heading into winter best idea is to put the smallest kite up instead of the bigger and depower, otherwise you might see what overpowered is.

I tend to agree with Plummet, you should be able to edge out gusts to hold more power, but as soon as I'm depowered I get a smaller kite.

For me overpowered is when you get those multiple lifts on a jump, you sheet out so you come down. You take so long to come down, hit the water at the speed of the wind and take close to a hundred meters to get back on your edge after landing

^^^ That is one stomach-churning video. IMO, kiting in any more than 35 real knots is for professionals or those with a death wish. I consider myself a pretty decent kiter and an experienced waterman but I have no interest in riding 40 knots, let alone 60. I've windsurfed in 40+ knots, but with kiting the risks are just too high for this little vegemite.

Hi guys,

I had a pretty good experience last Wednesday with my 17 meters Griffin.

It was at Canton Beach NSW on a westerly. Because the wind was so inconsistent (from 8 knots to probably 25), I had both of my kites on the shore ready to go. At some moment in time, the wind started picking up to the point where the kite wouldn't sustain its normal C shape, would be more like "I". At that point in time I had to QR, and of course, no problem whatsoever.....the kite fell in the water, I swam back to the shore, got my lines and kite back and everyone was happy. :)

Although, it's not a rec thing to do, no risk was involved.

The advice I give to other kiters about kiting in westerlies over winter is because im concerned about their well being and ive seen a lot of crazy $hit happen and most of it is in westerlies.I started kiting 11 years ago and you really had to respect the kites you used then,hardly any depower.Kiting gusty westerlies then was just crazy.I didnt start kiting westerlies till 2006 ,kites had a bit more depower then but still 4 line C kites.Had some real scary times myself then. I use bridle kites now and only kite westerlies to 30 knts,not fun being overpowered waiting to get flogged buy a gust.
The kites now have heaps of depower, some even 100% .
It gives learners a false sense of security because when the $hit hits the fan that kite isnt gunna be at 100% depower.
Agree with djdojo on all his points especially this

Windsurfing for me also above 30 REAL knots

No disrespect, but generalising from one experience that ended OK is foolish. With 80 hours on the water (as you posted somewhere else) you simply haven't had time to experience or witness the stuff that can go wrong. Have you seen someone wrap a bridle around a wingtip and start deathlooping? Have you seen someone snap a front line? Have you had these happen to you yet? If not, you'd be wise to still exercise caution especially in winter breezes.

I have and will kite in conditions gusting past 40. Generally in conditions like that its fluctuating anything from 25-45 knots. It certainly requires a different risk analysis.

Is it dangerous? yes it is. But it can be some of the most memorable kiting of your life. However newbies should not try it. those conditions are only for the experienced and even then the very experienced can be spanked badly.

A good rule of thumb to whether you should kite or not is to listen to your gut. if you are shiiting yourself then don't go out. If you get out there and your are still craaping your pants your outside your comfort zone. Call it a day and live to fight another.

Anything above 40 and you're stomach is not churning there is something wrong. Complacency is the precursor to incident!

Mr Teabagger is no Joe SLouch, wealth of knowledge and VERY skilled. His advice is sound. Having 80 hours experience is like having ten or twelve days on the slope. Oh, you say you want to try that black diamond run? Sure, go for it. Might be wind blown snow that you butter your way down. Next time might just have a flat section of ice and down you go. Do you have the experience to deal with that....? Nothing beats the years and what you learn after each mistake....

overpowered to me is after launching kite to 12 i am getting ANY body weightlessness through my centre lines with my arms just resting on the bar (maybe the middle of my depower throw) ..then get a smaller size.

to answer your question, basically you cant ease off of the power when you want to.. because no matter how far out your bar is (how dipped the nose of your kite is) enough wind is hitting the canopy to pull your weight.

think back to when you first started kiting and just got up and had a good run to either side and suddenly you wanted to stop.. just dunked your arse and dragged like a sea biscuit didnt you. and that was probably only 15 knots!!

I know guys, you are right. Many things can go wrong and sometimes I do things that don't really serve me well. But in the winter there are basically only Westerlies, then I shouldn't be kiting at all for the winter period? That is just depressing. I really want to get more time on the water and make the best of every session. That's all.

Thanks again for the good advice, I won't be flying the 17 then, unless is wind coming from the see somewhere.

Cheers,
Mike

We get a lot of gusty westerlies here my last session was 16-36 with explosive gusts,surf was just too good to pass on,basically the rule round here is small kite bigger board,its better to be lacking slightly in the lulls than to get hammered in the gusts,gotta say gusty days teach you how to be a way better rider but you have to know your limits depending on your experience and ability,most of my best rides have been in gusty 30-40+ knot winds.

Ive ridden with teabaggin quite a lot and he is a great kiter and experienced(pity he goes back to Sailboards once in a while, BTW Teabaggin, Lakes full!), some of the winds we get on the South coast are strong and the choices people make in kite size and the choice of not getting lessons is rediculious.

The kites on the market do depower alot but not to the extant of 100% (only if you pull your safety leash) but in the end if you dont want to get hurt like that vid posted, Let got of the bar! kite should, i say should, depower, if all your gear is set up correctly. A 17m in a westerly is a bit extreme, only if it is about 15knts on the gust otherwise im overpowered.

On that note the Westerlys are a coming! happy dayz are here again. Wind!
